It's only a matter of time, I can't imagine anybody can look at you with a straight face and tell you that in the millions/billions of solar systems/galaxies, there isn't another form of life advanced enough to communicate.

The question isn't whether there is one, but whether there is one within communication range. The one hundred billion galaxies that we are aware of at the moment are each huge as well, making finding a civilization within one the proverbial finding a needle in a haystack. Beyond that, the nearest galaxy is 2.5 million light years away. Even if we find a way to communicate exclusively through light, it will take millions of years just to send and recieve a simple message. And unless we find some way to get around the whole "nothing can travel faster than the speed of light" problem, we're certainly not visiting there.
